ROOF-ASPHALTING MACHINE.

Specification of Letters Patent Patented Dec; 22,1914.

Application filed September 4, 1913. Serial No. 788,064.

proofing material, such as asphaltum, and is designed to enable this operation to be performed on the roof of a building whereby the asphaltum impregnated paper may be applied direct to the roof while it is hot and 'in a favorable condition for such ap- 'plication.

In the usual practice of roofing with such material, tarred paper is applied to the roof and is mopped with hot asphaltum as each layer is laid. This process is troublesome and is unsatisfactory, in that paper which has been treated with a water-proofing material and allowed to cool, does not lie evenly; and further in applying subsequent layers of paper the intervenin asphaltum material cannot beevenly sprea by hand.

In the device, which is the subject of this application, the roll of paper, a tank of heated asphaltum, and the necessary rollers for passing the paper through the asphaltum and for smoothing over the surface of the paper the asphaltum taken up by it, are all mounted within a suitable frame on wheels, to which wheels a driving mechanism is applied by which the machine may be laterally traversed over a roof a measured distance such as will give the required overlap between each layer. The whole device is compactly arranged that it may be run close up to the party or fire wall of the building and the paper as cut off at the rolls will reach to the party wall and afford a flashing up it.

The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Figure 1 is a vertical longitudinal section of the machine taken in a plane at right anthe line of travel of the machine.

Fig. 2 is an enlarged detail perspective view of a portion of the mechanism. Fi 3 is an enlarged detail perspective view of? another portion of the invention. Fig. 4.- is an end elevation looking from left to right in Fig; 1. Figs. 5 and 6 are detail perspective views of one of the rollers.

In these drawings 2 represents a suitable frame which is mounted on wheels 3 secured on axles 1. Removably supported Within this frame 2 is a deep sheet metal asphaltum holding trough 5, which in cross section is rounded at the bottom and flared forward to the open top. Into this trough 5 the hot asphaltum is poured, and if found necessary, may be maintained at the required heat by artificial means such as by a hydrocarbon flame or an electric resistance coil. Within our present practice this provision has not been found necessary. A roller 6 of small diameter is supported in the bottom of this trough in hearings in the lower end of handle rods 7, the lower ends of which rods project beyond the bearing of the roller to such distance as will enable them to support the roller clear of the bottom of the trough. The bearing ends of the handle rods7move in vertical guides 8 so that the roller is supported in the tank so that it will not touch the sides, and the upper ends of the rods 7 are formed as handles by which the roller may be lifted up the guides 8 andfrom the trough, when required.

Mounted in open bearings on standards 11 secured on the upper sides of the frame 2 opposite to the trough is a roll of paper 10. Between this paper roll and the top of the trough two hollow feed rollers 12 and 13 are mounted in bearing blocks 1 1 which are freely movable in guide standards 15 secured to each side of the frame, the standards being angled from the paper roll, so that the paper 16 delivered from the upper side of the roll 10 may pass over the outer side of the upper roller 12, under the roller 6 in the trough and over the lower roller 13 without interfering. The rollers 12 and 13 are maintained hot by hot sand filled into them through an aperture 36 in the end of each, the maintenance of heat being necessary to prevent the asphaltum accumulating on the surfaces of the rollers. The upper roller rests upon-the surface of the lower roller and its weight is supplemented-to cess 21 is turned in the surface of the upper Y hold it in such contact by a weighted lever 18 pivotally connected at 19 to one side of each bearing standard and connected by a rod 20 to the upper bearing block 1-1. A reroller 12 about its midlcngth, the object of which recess is that a thicker layer of asphaltum shall be left along the mid-width of the paper where the edge of the next overlapping strip of paper is to be applied.

The-rollers '12 and 13 are driven by intermeshing gear wheels 22, 23 and by a crank handle 24 on the axle of the paper roller and a light frictional check or brake 37 is applied to the upper roll to prevent the paper overrunning the feed rollers. The axles 4 of the wheels are mounted in bearin forks 25, the stems 26 of which are threaded and provided with upper and lower nuts between which the fork is secured to the frame and by which the vertical distance of the wheels from the frame may be adjusted.

On the outwardly projecting end of the axles at of one of the wheels 3, issecured a gear wheel 27 in the teeth of which mesh those of another wheel 28, the axle 29 of Whichis mounted in hearings in a bracket 30 secured to the frame2 and in the teeth of this wheel 28 engages a pawl 32 pivotally connected to a handle lever 33 which is loosel Y mounted on the axle 29 on which the w eel 28 is secured. These gear wheels 27, 28 are so proportioned to the supporting wheels 3 that the movement of the handle lever 33within operative limits will rotate the driving wheel 3 through a distance sufficient to traverse the machine the width of the weather exposure of the paper.

Every precaution is taken to make the machine as light as possible fitting it for conveyance to and for use on the roof of a building. The height of the contact of the rollers 12 and 13 from the roof level and the distance of these rollers from the side of the machine to which the paper is delivered are such that when the paper is cut off close to the rollers a length of paper is left sufiicient to reach over the space occupied by the machine and to the party Wall and will leave about six inches of flashing up that wall.

In use, the machine is placed to move along the roof as close as practicable and parallel to one party wall 35, and the paper 16 is taken from the upper side of the roll 10, which is toward that party wall, is passed over the same side of the upper roller 12, and around the roller 6 which is immersed in the hot asphaltum within the trough 5. Thereafter the paper passes between the rollers 12 and 13 where any undesired surplus of the asphaltum is removed from the paper. Rotation of the rollers 12 and 13 feeds the paper through as described anddelivers it from the side of the machine farther from the wall 35, and as delivered it is carried by tongs to the other end of the roof and applied with a flashing 'to the party Wall at that end. When the length of paper which has passed from the machine has been laid evenly on the roof up to the machine the paper is cut adjacent to the rollers 1213 and the length reaching from the roof to the rollers is just sufficient to lay on the space occupied by the machine and to extend as a fiashing up the party wall 35.
